Fixed bed process desulfurizing tower capable of heating and dehumidifying

Abstract

The invention discloses a fixed bed process desulfurization tower capable of heating and dehumidifying, and belongs to the technical field of fixed bed process desulfurization, the fixed bed process desulfurization tower comprises a desulfurization tower body, the bottom of the desulfurization tower body is a discharge conical section, and the outer wall of the discharge conical section is sleeved with a heating pipeline; the heating pipeline comprises a plurality of layers of air pipes, each layer of air pipes are annularly arranged, the adjacent air pipes are communicated through air connecting pipelines, the air inlet end and the air outlet end of each layer of air pipes are oppositely arranged, and air flow of each layer of air pipes is divided into two paths from the air inlet end and then converged from the air outlet end.

Description

technical field [0001] The invention relates to the technical field of fixed-bed process desulfurization, in particular to a fixed-bed process desulfurization tower that can be heated and dehumidified. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the current desulfurization tower of fixed bed process, the desulfurizer used is mostly in the form of solid and large particles, and is generally not equipped with a heating system. In order to achieve better desulfurization effect and reduce the land area, it is usually used to reduce the diameter of the absorption tower , measures to increase the height of the absorption tower. When the height of the absorption tower is increased, a large amount of desulfurization agent powder will appear due to crushing and breaking of the desulfurizer during charging, which will accumulate on the discharge cone...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a fixed-bed process desulfurization tower that can be heated and dehumidified, so that the heating pipes are arranged in layers in rings, and the inlet end and the outlet end of each layer of air pipes are arranged opposite to each other, so that the steam is evenly distributed. Heating half of the wall panels in two ways at the same time can not only heat the cone bucket more evenly, but also minimize the number of interfaces and reduce the welding workload during installation, and remotely control the settings of valves, temperature sensors and other components. Accurately monitor data such as steam flow rate, consumption and temperature, and at the same time adjust the working status of the heating tube in real time based on big data analysis, which solves the problem of complex heating tube layout, uneven heating and inability to The problem of real-time adjustment of the working state of the heating tube
